Initial Ni-56 Masses in Type Ia Supernovae
Abstract
We infer initial masses of the synthesized radioactive nickel-56 in a sample of recent Type Ia supernovae applying a new formalism introduced recently by Khatami & Kasen. It is shown that the nickel masses we derive do not differ significantly from previous estimates based on the traditional Arnett-model. We derive the β parameter for our sample SNe and show that these are consistent with the fiducial value of ~1.6 given by Khatami & Kasen from SN Ia hydrodynamical simulations.
